ABSTRACT

1. Cellulitis and dermatitis are often seen in turkeys at slaughter and are, in many cases, reasons for rejection at meat inspection. Using the results of meat inspections and information about the housing conditions of the animals may provide information on causative factors in the development of cellulitis and dermatitis.

2. A census of two years of turkey production in a company including both fattening farms and an abattoir in the north of England was used to study the relationship between the prevalence of cellulitis/dermatitis and mechanical versus natural ventilation in the poultry house, litter type (long straw, short straw and wood shavings) and stocking density.

3. The overall prevalence of cellulitis and dermatitis in this population was 0.12 %, which was extremely low compared to reports in the literature. In mechanically ventilated houses, the odds of developing cellulitis and/or dermatitis was significantly higher than in naturally ventilated houses (Odds Ratio 3.18). Long straw had a protective effect compared to wood shavings (Odds Ratio 0.18).

4. The study showed that using slaughter data can be helpful in studying on-farm risk factors for disease development.

摘要

1.蜂窝织炎和皮炎通常在屠宰火鸡中见到，并且在许多情况下是肉类检查被拒绝的原因。利用肉类检查的结果和有关动物的居住条件的信息，可以提供有关蜂窝织炎和皮炎发展中的致病因素的信息。

2.在一家包括育肥场和英格兰北部屠宰场的公司中进行了两年的火鸡生产普查，以研究蜂窝织炎/皮炎的流行与家禽舍，垫料类型中机械通风与自然通风之间的关系。 （长稻草，短稻草和刨花）和放养密度。

3.该人群中蜂窝织炎和皮炎的总体患病率为0.12％，与文献报道相比极低。在机械通风的房屋中，发生蜂窝织炎和/或皮炎的几率显着高于自然通风的房屋（几率3.18）。与刨花相比，长稻草具有保护作用（几率0.18）。

4.研究表明，使用屠宰数据有助于研究农场中疾病发展的危险因素。
